The product obtained by the above named rooess is a substantially inadhesive peanut butter of a homogeneous plastic mass and composed of comminuted nuts from which a portion of the normal oil content has been extracted .and to which has been added to replace the extracted oil an edible hydrodnged oil, or in 11 i ing agent. is added may be that which was previous y extracted and hydrogenated or any other hydrogenated edible nut oil suitable for the purpose.
